Ermes Costello

エルメェス・コステロ

Ermes is one of Jolyne Cujoh's main allies. She is very prideful and loyal, preferring to act and think later. [Spoiler] She purposely ended up in jail to avenge the death of her elder sister Gloria. [/Spoiler] Whilst in Green Dolphin Street Prison, she acquires a Stand which she names 'Kiss' which allows her to place 'stickers' on items to duplicate them, but once the sticker is removed the two items smash together violently.
